Page 1 of 61 Abstract: The Content Assembly Mechanism (CAM) provides an open XML based system for using business rules to define, validate and compose specific business documents from generalized schema elements and structures. A CAM rule set and document assembly template defines the specific business context, content requirement, and transactional function of a document. A CAM template must be capable of consistently reproducing documents that can successfully carry out the specific transactional function that they were designed for. CAM also provides the foundation for creating industry libraries and dictionaries of schema elements and business document structures to support business process needs. The core role of the OASIS CAM specifications is therefore to provide a generic standalone content assembly mechanism that extends beyond the basic structural definition features in XML and schema to provide a comprehensive system with which to define dynamic e-business interoperability. Status: This document was last revised or approved by the Content Assembly Mechanism TC on the above date. The level of approval is also listed above. Check the “Latest Version” or “Latest Approved Version” location noted above for possible later revisions of this document. Technical Committee members should send comments on this specification to the Technical Committee’s email list. Others should send comments to the Technical Committee by using the “Send A Comment” button on the Technical Committee’s web page at http://www.oasis-open.org/committees/cam The CAM TC work is operating on an open license approach charter with unencumbered content, see the Technical Committee web page at http://www.oasis-open.org/committees/cam/charter.php For information relating to disclosure of patents pertaining to the CAM TC work, and if any such contributing member statements exist, please refer to the Intellectual Property Rights section of the Technical Committee web page (http://www.oasis-open.org/committees/cam/ipr.php The non-normative errata page for this specification is located at http://www.oasis- open.org/committees/cam OASIS-CAM-Specifications-1_1-RC-014-030508.doc 26 February 2007 Copyright © OASIS® 1993–2007.
